Drawing is a metalworking process which uses tensile forces to stretch metal. It is broken up into two types: sheet metal drawing and wire, bar, and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis. For wire, bar, and tube drawing the starting stock is drawn through a die to reduce its diameter and increase its length. Drawing is usually done at room temperature, thus classified a cold working process, however it may be performed at elevated temperatures to hot work large wires, rods or hollow sections in order to reduce forces.
Famous quotes containing the word drawing:
“Ye whose clay-cold heads and luke-warm hearts can argue down or mask your passions—tell me, what trespass is it that man should have them?... If nature has so wove her web of kindness, that some threads of love and desire are entangled with the piece—must the whole web be rent in drawing them out?”
—Laurence Sterne (1713–1768)
